This paper outlines methods to obtain, verify, and deploy VMware vSphere Hypervisor (ESXi) 6.7 build releases from 2021 for legitimate lab, research, and preservation purposes. It covers official download channels and archive access, integrity verification (checksums and GPG where available), license considerations, safe offline installation practices, known compatibility considerations with modern hardware and drivers, and legal/ethical guidelines for software archival and reproducible research.

Note: VMware vSphere Hypervisor (ESXi) 6.7 reached general availability before 2021 and received updates through that period. If you need the 6.7 build released around 2021, follow the steps below to locate and download the installer and supporting files safely and legally.

For a paper written in or about 2021, you must note that VMware ESXi 6.7 reached "General Support End of Life" on October 15, 2022.

However, in 2021, ESXi 6.7 was still under support but was considered an "older" generation compared to ESXi 7.0 Update 3 (released in late 2021).

Why downloading 6.7 in 2021 was difficult: In late 2020/early 2021, Broadcom announced its acquisition of VMware. By 2021, VMware had already transitioned the free version of ESXi (Hypervisor) to a 60-day trial model. The fully free "perpetual" license keys for ESXi 6.7 were discontinued or hidden behind the "VMware Customer Connect" portal.

VMware keeps old patches available under maintenance.
